+
+
+### Deprecations and Removals
+- [#6484](https://github.com/rasahq/rasa/issues/6484): NLG Server
+ - Changed request format to send `response` as well as `template` as a field. The `template` field will be removed in Rasa Open Source 3.0.0.
+
+ `rasa.core.agent`
+ - The terminology `template` is deprecated and replaced by `response`. Support for `template` from the NLG response will be removed in Rasa Open Source 3.0.0. Please see [here](nlg.mdx) for more details.
+
+ `rasa.core.nlg.generator`
+ - `generate()` now takes in `utter_action` as a parameter.
+ - The terminology `template` is deprecated and replaced by `response`. Support for `template` in the `NaturalLanguageGenerator` will be removed in Rasa Open Source 3.0.0.
+
+ `rasa.shared.core.domain`
+ - The property `templates` is deprecated. Use `responses` instead. It will be removed in Rasa Open Source 3.0.0.
+ - `retrieval_intent_templates` will be removed in Rasa Open Source 3.0.0. Please use `retrieval_intent_responses` instead.
+ - `is_retrieval_intent_template` will be removed in Rasa Open Source 3.0.0. Please use `is_retrieval_intent_response` instead.
+ - `check_missing_templates` will be removed in Rasa Open Source 3.0.0. Please use `check_missing_responses` instead.
+
+ Response Selector
+ - The field `template_name` will be deprecated in Rasa Open Source 3.0.0. Please use `utter_action` instead. Please see [here](components.mdx#selectors) for more details.
+ - The field `response_templates` will be deprecated in Rasa Open Source 3.0.0. Please use `responses` instead. Please see [here](components.mdx#selectors) for more details.
+
+### Improvements
+- [#7022](https://github.com/rasahq/rasa/issues/7022): The following endpoints now require the existence of the conversation for the specified conversation ID, raising an exception and returning a 404 status code.
+
+ * `GET /conversations/<conversation_id:path>/story`
+
+ * `POST /conversations/<conversation_id:path>/execute`
+
+ * `POST /conversations/<conversation_id:path>/predict`
+- [#7438](https://github.com/rasahq/rasa/issues/7438): Simplify our training by overwriting `train_step` instead of `fit` for our custom models.
+
+ This allows us to use the build-in callbacks from Keras, such as the 
+ [Tensorboard Callback](https://www.tensorflow.org/api_docs/python/tf/keras/callbacks/TensorBoard), 
+ which offers more functionality compared to what we had before. 
+
+ :::warning
+ If you want to use Tensorboard for `DIETClassifier`, `ResponseSelector`, or `TEDPolicy` and log metrics after 
+ every (mini)batch, please use 'batch' instead of 'minibatch' as 'tensorboard_log_level'.
+- [#7578](https://github.com/rasahq/rasa/issues/7578): When `TED` is configured to extract entities `rasa test` now evaluates them against the labels in the test stories. Results are saved in `/results` along with the results for the NLU components that extract entities.
+- [#7680](https://github.com/rasahq/rasa/issues/7680): We're now running integration tests for Rasa Open Source, with initial coverage for `SQLTrackerStore` (with PostgreSQL),
+ `RedisLockStore` (with Redis) and `PikaEventBroker` (with RabbitMQ). The integration tests are now part of our
+ CI, and can also be ran locally using `make test-integration`
+ (see [Rasa Open Source README](https://github.com/RasaHQ/rasa#running-the-integration-tests) for more information).
+- [#7763](https://github.com/rasahq/rasa/issues/7763): Allow tests to be located anywhere, not just in `tests` directory.
+- [#7893](https://github.com/rasahq/rasa/issues/7893): Model configuration files are now validated whether they match the expected schema.
+- [#7952](https://github.com/rasahq/rasa/issues/7952): Speed up `YAMLStoryReader.is_key_in_yaml` function by making it to check if key is in YAML without 
+ actually parsing the text file.
+- [#7953](https://github.com/rasahq/rasa/issues/7953): Speed up YAML parsing by reusing parsers, making the process of environment variable interpolation optional,
+ and by not adding duplicating implicit resolvers and YAML constructors to `ruamel.yaml`
+- [#7955](https://github.com/rasahq/rasa/issues/7955): Drastically improved finger printing time for large story graphs
+- [#8000](https://github.com/rasahq/rasa/issues/8000): Remove console logging of conversation level F1-score and precision since these calculations were not meaningful.
+
+ Add conversation level accuracy to core policy results logged to file in `story_report.json` after running `rasa test core` or `rasa test`.
+- [#8100](https://github.com/rasahq/rasa/issues/8100): Improved the [lock store](lock-stores.mdx) debug log message when the process has to
+ queue because other messages have to be processed before this item.
+
+### Bugfixes
+- [#4612](https://github.com/rasahq/rasa/issues/4612): Fixed the bug that OR statements in stories would break the check whether a model needs to be retrained
+- [#7063](https://github.com/rasahq/rasa/issues/7063): Update the spec of `POST /model/test/intents` and add tests for cases when JSON is provided.
+
+ Fix the incorrect temporary file extension for the data that gets extracted from the payload provided
+ in the body of `POST /model/test/intents` request.
+- [#7113](https://github.com/rasahq/rasa/issues/7113): Fix for the cli command `rasa data convert config` when migrating Mapping Policy and no rules.
+
+ Making `rasa data convert config` migrate correctly the Mapping Policy when no rules are available. It updates the `config.yml` file by removing the `MappingPolicy` and adding the `RulePolicy` instead. Also, it creates the `data/rules.yml` file even if empty in the case of no available rules.
+- [#7470](https://github.com/rasahq/rasa/issues/7470): Allow to have slots with values that result to a dictionary under the key `slot_was_set` (in `stories.yml` file).
+
+ An example would be to have the following story step in `stories.yml`:
+ ```yaml
+ - slot_was_set:
+ - some_slot:
+ some_key: 'some_value'
+ other_key: 'other_value'
+ ```
+ This would be allowed if the `some_slot` is also set accordingly in the `domain.yml` with type `any`.
+- [#7662](https://github.com/rasahq/rasa/issues/7662): Update the fingerprinting function to recognize changes in lookup files.
+- [#7932](https://github.com/rasahq/rasa/issues/7932): Fixed a bug when interpolating environment variables in YAML files which included `$` in their value. 
+ This led to the following stack trace:
+
+ ```
+ ValueError: Error when trying to expand the environment variables in '${PASSWORD}'. Please make sure to also set these environment variables: '['$qwerty']'.

+ return yaml_parser.load(content) or {}
+ File "rasa/shared/utils/io.py", line 314, in env_var_constructor
+ " variables: '{}'.".format(value, not_expanded)
+ ```
+- [#7949](https://github.com/rasahq/rasa/issues/7949): The REQUESTED_SLOT always belongs to the currently active form.
+
+ Previously it was possible that after form switching, the REQUESTED_SLOT was for the previous form.
+- [#96](https://github.com/rasahq/rasa/issues/96): Update the `LanguageModelFeaturizer` tests to reflect new default model weights for `bert`, and skip all `bert` tests 
+ with default model weights on CI, run `bert` tests with `bert-base-uncased` on CI instead.
+
+### Miscellaneous internal changes
